Read temp sensors from command line

[67comet]

This is a great little script for us headless guys.

I run into an error however (and this is exactly how it prints in the terminal via ssh).

I'm not sure if I'm supposed to have something to run bc but it kicks that error out every time.

I'd love to read my temps in F*.

Thanks for any goodness...

P.S. The code I've got verbatim:

Code: Select all

for src in arm core h264 isp v3d uart pwm emmc pixel vec hdmi dpi ; do echo -e "$src:\t $(/opt/vc/bin/vcg$

that line is truncated

it should be

Code needs GNU bc arbitrary precision calculator language, shorter bc.
On raspbian or debian:

Code: Select all

apt-get update && apt-get install bc

Jordi just pushed some changes to monitorix that logs to an rrd database many if not all of the sensor output of the pi. Screenshot:

I'm not an expert but I think you can read it from

Code: Select all

cat /sys/class/thermal/thermal_zone0/temp 

Divide by 1000 will give temperature on board.

I don't know if any of you are familiar with conky.

apt-get install conky-all

It works for X and ncurses. Yet, I have not tried ncurses ability.
